Thanks.

I just downloaded the source here:
http://vault.centos.org/7.5.1804/os/Source/SPackages/kernel-3.10.0-862.el7.src.rpm

And to my surprise, I don't even see mce as a kernel parameter based on the
command you suggested:
$ grep -r "early_param" . | grep mce
$

So it seems like "early_param" only covers some kernel parameters but not
all.

Thanks for your suggestion tho!
